Step-by-step explanation:
2x + 2x + 72° = 180°
4x = 108°
x = 27°
3000 words
450 words in 3 minutes is 150 words in 1 minute. 20 minutes = 1 times 20.
1 minute = 150 words so 150 words times 20 minutes = 3000 words.
angle don+angle gil=90°
don+ 74°=90°
don=90°-74°
don=16°
angle e + angle a=180°
128°+angle a=180°
angle a=180°-128°
angle a=52°
